Title: VERITAS Upper Limit on the Very High Energy Emission from the Radio Galaxy NGC 1275

Abstract

We report the recent detection by the Fermi γ-ray space telescope of high-energy γ-rays from the radio galaxy NGC 1275 that makes the observation of the very high energy (VHE: E>100 GeV) part of its broadband spectrum particularly interesting, especially for the understanding of active galactic nuclei with misaligned multi-structured jets. The radio galaxy NGC 1275 was recently observed by VERITAS at energies above 100 GeV for about 8 hr. No VHE γ-ray emission was detected by VERITAS from NGC 1275. Finally, a 99% confidence level upper limit of 2.1% of the Crab Nebula flux level is obtained at the decorrelation energy of approximately 340 GeV, corresponding to 19% of the power-law extrapolation of the Fermi Large Area Telescope result.

VERITAS UPPER LIMIT ON THE VERY HIGH ENERGY EMISSION FROM THE RADIO GALAXY NGC 1275

Journal Article Acciari, V A ; Benbow, W ; Aliu, E ; ... - Astrophysical Journal (Online)

The recent detection by the Fermi gamma-ray space telescope of high-energy gamma-rays from the radio galaxy NGC 1275 makes the observation of the very high energy (VHE: E>100 GeV) part of its broadband spectrum particularly interesting, especially for the understanding of active galactic nuclei with misaligned multi-structured jets. The radio galaxy NGC 1275 was recently observed by VERITAS at energies above 100 GeV for about 8 hr. No VHE gamma-ray emission was detected by VERITAS from NGC 1275.

Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy γ -rays

Journal Article Aleksić, J. ; Ansoldi, S. ; Antonelli, L. A. ; ... - Astronomy and Astrophysics

The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) γ-ray emitter by MAGIC, is one of the few non-blazar active galactic nuclei detected in the VHE regime. The purpose of this work is to better understand the origin of the γ-ray emission and locate it within the galaxy. We studied contemporaneous multifrequency observations of NGC 1275 and modeled the overall spectral energy distribution. We analyzed unpublished MAGIC observations carried out between October 2009 and February 2010, and the previously published observations taken between August 2010 and February 2011. Here, we studied the multiband variabilitymore »« less

VERY HIGH ENERGY GAMMA-RAY-INDUCED PAIR CASCADES IN BLAZARS AND RADIO GALAXIES: APPLICATION TO NGC 1275

Journal Article Roustazadeh, P ; Boettcher, M - Astrophysical Journal

Recent blazar detections by HESS, MAGIC, and VERITAS suggest that very high energy (VHE; E > 100 GeV) {gamma}-rays may be produced in most, if not all, types of blazars, including those that possess intense circumnuclear radiation fields. In this paper, we investigate the interaction of nuclear VHE {gamma}-rays with the circumnuclear radiation fields through {gamma}{gamma} absorption and pair production, and the subsequent Compton-supported pair cascades. We have developed a Monte Carlo code to follow the spatial development of the cascade in full three-dimensional geometry and calculate the radiative output due to the cascade as a function of viewing anglemore »« less

γ-ray spectral evolution of NGC 1275 observed with FERMI large area telescope

Journal Article Kataoka, J. ; Stawarz, Ł. ; Cheung, C. C. ; ... - The Astrophysical Journal

Here, we report on a detailed investigation of the high-energy γ-ray emission from NGC 1275, a well-known radio galaxy hosted by a giant elliptical located at the center of the nearby Perseus cluster. With the increased photon statistics, the center of the γ-ray-emitting region is now measured to be separated by only 0.46 arcmin from the nucleus of NGC 1275, well within the 95% confidence error circle with radius ≃1.5 arcmin. Early Fermi Large Area Telescope (LAT) observations revealed a significant decade-timescale brightening of NGC 1275 at GeV photon energies, with a flux about 7 times higher than the onemore »« less

VERITAS 2008-2009 MONITORING OF THE VARIABLE GAMMA-RAY SOURCE M 87

Journal Article Acciari, V A ; Benbow, W ; Aliu, E ; ... - Astrophysical Journal

M 87 is a nearby radio galaxy that is detected at energies ranging from radio to very high energy (VHE) gamma rays. Its proximity and its jet, misaligned from our line of sight, enable detailed morphological studies and extensive modeling at radio, optical, and X-ray energies. Flaring activity was observed at all energies, and multi-wavelength correlations would help clarify the origin of the VHE emission. In this paper, we describe a detailed temporal and spectral analysis of the VERITAS VHE gamma-ray observations of M 87 in 2008 and 2009. In the 2008 observing season, VERITAS detected an excess with amore »« less
